According to the disclosure of the present document, when the inter-prediction type of the current block indicates biprediction, weight index information for a candidate in a merge candidate list or sub-block merge candidate list can be derived, and coding efficiency can be raised.
Legal claims defining the scope of protection, as filed with the USPTO.
9. The image decoding method of claim 1, wherein based on a case that the constructed affine merge candidate is generated based on {CP1, CP2, CP3}, the weight index for the constructed affine merge candidate is set equal to a weight index for the CP1, wherein the CP2 is related to a bottom-left corner of the current block.
12. The image encoding method of claim 11, wherein based on a case that the constructed affine merge candidate is generated based on {CP1, CP2, CP3}, the weight index for the constructed affine merge candidate is set equal to a weight index for the CP1, wherein the CP2 is related to a bottom-left corner of the current block.
